U0548 Invalid Data Received From Seat Control Module F
For seat control module F no manufacturer publishes an official assignment, and U0548 appears in no bulletin. Ford's naming shows how far seat letters reach: B for the front passenger, G and H for multi-contour units, J for third-row power folding and K/L for the second-row power seats of the 2025 Navigator (SSM 54226), so F is one more seat node, possibly in a rear row. A Gentherm-family patent describes a common split in which a backrest module takes commands from the main seat module over a dedicated line, a layout in which bad data from a secondary unit is entirely possible. U0548 means unit F still answers but its content fails the checks; U0247 stands for lost contact. Heating, folding or adjustment of that seat may then be blocked.
